Article Synopsis
- This work presents a comparative study of electrical and optical methods used to characterize a redox-labeled DNA sensing platform and evaluate its signal transduction efficiency.
- The study utilized conventional electrochemical techniques—cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS)—and contrasted these with optical measurements based on surface plasmon waves during similar electrochemical conditions.
- Results showed that optical impedance spectroscopy is a viable and effective method for developing a biosensing strategy that is less affected by non-faradaic interference, highlighting its potential in enhancing DNA-hybridization sensing applications.
Evaluation of the Accuracy of a New Geometric Approach to Implant Guidance.
Int J Oral Maxillofac Implants
March 2022
Purpose: Implant surgical guides are often fabricated using CBCT technology. In this study, an alternative technique is proposed. The aim of this in vitro study was to compare the accuracy of the guide sleeve corrections of a geometric approach to guided surgery to the accuracy of in vitro studies of stereolithographic guides.

In this report, we describe a case of partial bilateral rupture of the infraspinatus muscle, an unusual injury. Clinical signs included lameness of the left thoracic limb after training.

The global effort undertaken by WHO aims to reduce road traffic deaths in order to meet goal number 3.4 of the sustainable development goals.

Materials And Methods: Eighty tapered designed implants (3.8 × 10 mm) were inserted following osteotomies created in solid rigid polyurethane foam (simulating bone type II) and cellular rigid polyurethane foam (simulating bone type IV).
Aim: Application of quantitative stable isotope-labelling chemistries and mass spectrometry (MS) to determine alterations in gingival crevicular fluid (GCF) proteome in periodontal disease.
Material And Methods: Quantitative proteome of GCF from 40 healthy individuals versus 40 patients with periodontal disease was established using 320 GCF samples and stable isotope-labelling reagents, ICAT and mTRAQ, with MS technology and validated by enzyme-linked immunosorbent methods.
Results: We have identified 238 distinct proteins of which 180 were quantified in GCF of both healthy and periodontal patients with additional 26 and 32 distinct proteins that were found only in GCF of healthy or periodontal patients.
